Detailed description of the invention

In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.

With reference to Fig. 1, the invention provides a kind of hand-held lamp for repairing, it includes lamp body 100 and the hook 200 being located on lamp body 100. In conjunction with Fig. 2, Fig. 3, lamp body 100 is in column, and the center of column lamp body 100 offers a containing cavity 110, and the bottom of containing cavity 110 is provided with elastic component 300, and hook 200 is placed in containing cavity 110, and the bottom of hook 200 is fixed on elastic component 300. Present invention, it is desirable to when hanging use and maintenance lamp, hook 200 is pulled out; When not needing to hang, hook 200 is by elastic component 300 pulling force effect retraction containing cavity 110 automatically, it is achieved link up with built-in placement; This built-in hook structure, the potential safety hazard existed when fundamentally solving conventional light fixture head fixed hook, it is to avoid inadvertently fall off and hurt sb.'s feelings and misoperation scratch personnel and equipment, substantially increase the safety of production operation.

Referring again to Fig. 4, in the present invention, lamp body 100 includes column cooling stand 120, be located on column cooling stand 110 outer wall LED light source 130 and the translucent cover 140 covering at outside LED light source 130. Above-mentioned containing cavity 110 is located in column cooling stand 120. Referring again to Fig. 2, for the structural representation of column cooling stand 120. In figure, column cooling stand 120 is polygonal cylinder for cross section, as such, it is possible to arrange more LED light source 130 in column cooling stand 120 outside wall surface, thus strengthening the brightness of lamp for repairing. Containing cavity 110 is axially located in column cooling stand 120, the inwall of containing cavity 110 be provided with along column cooling stand 120 length direction extend chute 111; In conjunction with Fig. 3, hook 200 being arranged with a limited block 400, limited block 400 edge is provided with and can be stuck in chute 111, and the slide block 410 that can slide along chute 111. When hook is 200 when being drawn out or when automatically retracting, slide block 410 coordinates, with chute 111, slips, plays guiding, cushioning effect to linking up with 200, it is to avoid link up with 200 quickly pulled out or fast retractile and make elastic component 300 lose efficacy because excessively pullling;And when linking up with 200 and being drawn out suspension, hook 200 is also carried out spacing by the item effect of supporting of limited block 400 top shoe 410 and the chute 111 of containing cavity 110, it is to avoid it is left and right in containing cavity 110 rocks, thus ensureing the reliable use of lamp for repairing.

Referring again to Fig. 2, in the present embodiment, the inwall of containing cavity 110 being interval with the some radiation rib 112 extended along column cooling stand 120 length direction, the gap between adjacent heat radiation rib 112 forms above-mentioned chute 111. Adopt this structure, radiation rib 112 is set on the one hand, strengthen the inner wall surface area of containing cavity 110, enhance the heat-sinking capability of column cooling stand 120, improve the radiating efficiency of LED light source 130; On the other hand, do not need additionally to arrange chute 111, directly adopt the gap between adjacent heat radiation rib 112 to be snapped in by slide block 410, simplify structure.

Specifically, the cross section of containing cavity 110 is circular, and above-mentioned radiation rib 112 is uniformly distributed on circular inner wall; Limited block 400 is in disk form, and slide block 410 is multiple, in the present embodiment, slide block 410 is eight, and two be one group of setting, often leaving, between two slide blocks 410 in group, the gap being available for radiation rib 112 insertion, four groups of slide blocks 410 are uniformly distributed on the circumference of limited block 400. Herein, the cross section of containing cavity 110 and limited block 400 are arranged to the toroidal matched, so, limited block 400 does not need a point direction when being installed on hook 200, directly putting, and slide block 410 does not need to align with fixing chute 111 yet, it coordinates with the grafting of arbitrary chute 111. So, simplify operation, improve efficiency of assembling.

Referring again to Fig. 3, limited block 400 is provided with centre bore 420, and hook 200 is by traverse in centre bore 420, and limited block 400 is provided with the arcuate socket 430 of two hollow outs, and these two arcuate sockets 430 are symmetrical arranged centered by centre bore 420. In the present embodiment, limited block 400 is the laminated structure of thinner thickness, itself there is certain elasticity, and the arcuate socket 430 of two hollow outs is set herein, such void region also becomes elastically-deformable space, being greatly enhanced the elastic deformation ability of limited block 400, such limited block 400 can occur elastic deformation to make mobile more smooth and easy when meeting frictional force when motion upper and lower with hook 200.

Referring again to Fig. 4, a through hole 121 is offered at the center of column cooling stand 120, and the bottom of column cooling stand 120 is provided with the bottom 500 hiding through hole 121, and through hole 121 and bottom 500 enclose the containing cavity 110 of formation, and elastic component 300 is fixed on bottom 500. Column cooling stand 120 is not designed to totally-enclosed, but is blocked by bottom 500, so, is easy to the radiation rib 112 in processing containing cavity 110 on the one hand; On the other hand, also allow for elastic component 300 and hook 200 are installed, during installation, after hook 200 and elastic component 300 can being fixed on bottom 500, then bottom 500 is fixed on through hole 121 bottom.

Further, protruding out a boss 510 inside bottom 500, boss 510 is provided with a fixing hole 511, and the bottom opening place of through hole 121 is provided with a step 122, and bottom 500 is embedded in step 122, and the boss 510 inside bottom 500 stretches in through hole 121. Being embedded in step 122 by bottom 500, make bottom 500 keep concordant with the bottom of column cooling stand 120, and boss 510 stretches in through hole 121, also make bottom 500 coordinate with through hole 121 tightr, sealing property is better.In the present embodiment, elastic component 300 is a spring, and an end hook of spring is located on fixing hole 511, and the other end is connected with one end of hook 200.

In the present embodiment, bottom 500 is locked by screw 600 with step 122 corresponding position. Adopting screw, demolition, installation therebetween are all more convenient.

Referring again to Fig. 4, in the present embodiment, when hand-held lamp for repairing does not work, hook 200 is limited by elastic component 300 pulling force to be retracted in containing cavity 110, now, links up with 200 and does not expose, it is to avoid scratch personnel or equipment; With reference to Fig. 5, when use and maintenance lamp need to be hung, hook 200 pull-out is hung, simple to operate, easy to use.

These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
